Coronary artery disease (CAD) is the most common cause of death in the developed world, responsible for about one (1) in every five (5) deaths. This is one of cardiovascular diseases that comprise the four (4) major non-communicable diseases in the Philippines alongside cancers, chronic obstructive pulmonary diseases and diabetes mellitus. The Philippines is one of the 23 selected countries that contribute around 80% of the total mortality burden attributable to chronic diseases in developing countries. In 2015, the Bicol Regional Training and Teaching Hospital (BRTTH) Cardiac Catheterization laboratory unit had a total of 212 patient who underwent coronary angiogram and angioplasty. Out of 212, 51 patients underwent coronary angioplasty.

The study was aimed to determine the correlation of ECG and angiographic findings among eighty eight (88) stable patients  patients who underwent angiogram or angioplasty in BRTTH. This was deemed to bridge the gap between patients diagnosed with coronary artery disease and aid in their decision-making to undergo coronary angiogram or angioplasty proximate to the time of diagnosis in order to prevent further adverse outcomes. Patients were monitored while inside the hospital excluding their outcome beyond admission. Data was analyzed using descriptive statistics. The most common ECG changes documented were ST depression (21), T wave inversion and LVH (8 each), poor R wave progression and RBBB (5 each), atrial fibrillation (3), LBBB (2), and one each for AV block and atrial abnormality. there was no correlation between ECG changes and coronary angiogram. Among the patients enrolled in the study, There were thirty one (31) patients (35.23%) with normal ECG who had abnormal angiographic findings.

The ECG and angiographic findings was compared using Chi-square (x2) test, X2 (1) = 0.26, p
